Respuesta :
All three would decrease the size of the population of the organism. If an organism suddenly has a new predator, the organism's population will decline and it is likely that the members of the prey's population would disperse in an attempt to survive. Disease would just kill off the population in general, maybe the organism's population would distribute itself differently in order to avoid catching the disease. Competition would decrease the amount of food, water, and/or land available to the organism's population causing it to decrease or change habitats in an attempt to find another food source
The predation, disease, and competition has a great impact on population of an organism.
Predation, disease, and competition decrease the population of an organism. Predation is the killing of one organism by the other organism, disease harms the organism by causing infection and kills that organism which leads to decrease in the population of an organism. Competition for resources also leads to the decrease in the population of an organism so in short we can conclude that predation, disease, and competition adversely affected the population.
